OKEECHOBEE, Fla. — A woman was arrested for allegedly forcing her 12-year-old daughter into prostitution and trading a 14-year-old daughter for a car.

The 39-year-old woman was charged with aggravated child abuse and sexual performance by a child. Both girls have been turned over to the Department of Children &amp; Families.

The youngest girl and her mother were living out of their car, and would sell sex for food and an occasional shower at the men's homes, according to a report by Okeechobee County Sheriff's Office Detective K.J. Ammons.

The youngest daughter is three months pregnant, the report said; she was 11 when her mother first forced her to have sex with a man. The older daughter refused to be a prostitute and was allegedly sold for a car.

"She was sold to a man for a Mercury Cougar," Ammons said. "But he never gave the mother the vehicle." He was arrested in the case.

The youngest girl told detectives her mother took them out of school. "She said she was a good student and made A's and B's, and all she wants to do is go back to school," he said.
